@juku That depends on the diameter of the pulley. I specifically chose F608 bearings for pulleys in my printer because they meet the Gates recommended minimum of 9 teeth in contact with a smooth pulley surface. I get no print artifacts from the smooth pulleys.
Hi, i´ve already my V0.1 running. It was the mini afterburner. I´ve just calibrated the extruder...started with 400 ... ended up with 780.
Till now there was nothing melted. I´m using the LDO 36STH20-1004. Running with 900mA
What i had now is that my Duet Board doesn´t like to stay without cooling behind the panels. That socks really.
I´ve to design now a cooling fan for it. Really bad on this little thing with no space.
@fma
Seriously trying to use that to drive a nema34!!!!.
Right. You need a DM860T type driver (110vdc) and 80vdc minimum power supply size for proper good use of it.
If you're not going to do it properly or can't do the math. I suggest you find a new hobby.
@fma@dc42 could you use the conditional Gcode to run a movement that starts and stops with an input/button press?

To do that, we would need several more things:
A method of specifying that an axis created using M584 is a continuous rotation axis (continuous rotation axes are already supported internally);
A way of creating a daemon GCode task that executes a loop continuously;
A way of specifying that specific motion commands (or motion commands for a particular axis) should go into the second movement queue;
Bingo! In fact, it makes sens, as the pwm output only pulls the signal to ground... So, it has to be pulled up in order to have a high state voltage value!
I think I had this resistor with RRF2, but as I didn't use the servo since several months, I forgot that 😕
